1不同类型热液金矿系统的流体包裹体特征显示文摘为使流体包裹体研究结果得到较好的解释,避免矿床地质描述与流体包裹体研究结果发生矛盾,本文试图以金矿床为例,建立科学而简便易行的矿床地质与包裹体特征之间的链接。为此,本文简单评述了现有金矿床成因分类方案,建议以主导成矿系统发育的地质作用特征划分5种类型:①浆控高温热液型,包括斑岩型、爆破角砾岩型、铁氧化物型、夕卡岩型等岩浆热液型矿床;②造山型,即变质热液型;③浅成低温热液型——陆相火山岩-次火山岩中的改造热液型;④微细粒浸染型(卡林型或/类卡林型)——沉积岩容矿的改造热液型;⑤热水沉积型(VMS 型和 SEDEX 型)——水下喷出地表的改造热液型。然后,分别介绍了5类成矿系统的标志性地质和流体包裹体特征,找出了它们之间具有成因标志意义的关键性差异;将成矿流体分为改造、变质和岩浆3个端元性成分,发现多数热液矿床具有多阶段多因复成的特点,晚阶段流体均为改造热液或有大量改造热液注入,因此指出,晚阶段的流体、蚀变和矿化特征不能用于判别矿床成因和类型,只有早阶段的特征才能准确指示矿床成因和类型。改造热液以低温、低盐度、低 CO_2含量为特征,主要来自大气降水和/或海水;变质热液以中温、低盐度、高 CO_2含量为特征,而岩浆热液则以高温、高盐度、高 CO_2含量为特征;岩浆热液矿床发育含多种子晶包裹体和高盐度富 CO_2的包襄体,变质热液矿床发育低盐度富 CO_2包裹体,改造热液矿床总体缺乏含子晶包裹体和富/含 CO_2包襄体,大量发育水溶液包裹体。最后,讨论了各类成矿系统发育的岩石圈构造背景,如造山型矿床形成于地壳挤压造山-变质-隆升过程,热水沉积型矿床形成于地壳拉张成盆过程,古生代或更早的浅成低温热液型矿床只能保存在增生型造山带等,提出矿床及其包裹体是研究大陆动力学的理想探针。陈衍景 倪培 范宏瑞 F Pirajno 赖勇 苏文超 张辉 2007岩石学报2007,23,9:535
2不同类型热液金矿系统的流体包裹体特征显示文摘 针对当前一些文献未能较好解释包裹体研究结果的科学涵义,甚至出现矿床地质描述与流体包裹体研究结果自相矛盾的现象,本文试图以金矿床为例,建立科学而简便易行的矿床地质与包裹体特征之间的链接.为此,本文简单评述了现有金矿床成因分类方案(表1),建议以主导成矿系统发育的地质作用特征划分5种类型:①浆控高温热液型,包括斑岩型、爆破角砾岩型、铁氧化物型、夕卡岩型等岩浆热液型矿床;②造山型,即变质热液型;③浅成低温热液型--陆相火山岩-次火山岩中的改造热液型;④微细粒浸染型(卡林型或/类卡林型)--沉积岩容矿的改造热液型;⑤热水沉积型(VMS型和SEDEX型)--水下喷出地表的改造热液型'VMS型和SEDEX型.指出了各类矿床成矿构造模型(图1)……陈衍景 倪培 范洪瑞 F Pirajno 赖勇 苏文超 张辉 2007矿物学报2007,,z1:5
